This really depends on how much you already know and how much research you are supposed to do to answer the questions. Here are a couple I would be interested in if I were the one writing:

In what ways did Malcolm's words and actions change after he came back from Mecca? I know that he changed his mind about white people on that trip, but I do not know much about how his actions changed when he started to reject the Nation of Islam's more racist teachings.

What evidence is there to prove or disprove the idea that the leadership of the Nation of Islam ordered Malcolm's killing.
